Position an oven rack in the middle of the oven and heat to 450℉.
Remove any of the tough side muscles from the scallops by pinching them between your fingers and pulling them away. Then rinse the scallops with cold water in a sieve or strainer, and pat dry with paper towels.
Melt 2 tablespoons of the butter in a 10-inch skillet over medium heat. Add the panko and crushed crackers and stir frequently for 2 minutes, until golden brown. Stir in the hot sauce then remove to a large bowl. Stir the parmesan and parsley into the crumbs, and set aside 1/4 cup to use for the topping.
Melt the remaining butter in the pan then add the garlic and cook, stirring constantly, for 30 seconds. Add the tomatoes, salt, and pepper and cook until almost dry, 3 minutes. Pour in the wine and cook another 2 minutes, or until most of the wine has evaporated. Remove from the heat to cool for about 5 minutes.
Add the scallops and the cooled tomato mixture to the breadcrumb bowl and toss to thoroughly incorporate.
Divide the filling evenly amongst the shells or ramekins, then top each with a sprinkling of the reserved crumbs.
Bake for 8 minutes, or until golden brown on top. Cool for 5 minutes before serving.
